Method

To make the lasagne filling, set the oven to hot, 220°C (425°F, gas mark 7). Mix all the vegetables in a large roasting tin with the herbs, oil and plenty of seasoning. Roast for about 25 mins, then turn them and roast for another 20 mins.

Meanwhile, dissolve the vegetable bouillon in 550ml (18fl oz) boiling water. Add the lentils and leave them to soak for 30 mins.

To make the lasagne sauce, melt the spread in a saucepan, add the flour, cornflour and mustard and cook for 1 min. Gradually stir in the soya milk a little at a time. Stir in cheese, bring to the boil and boil for a few minutes. Whisk it well, but don’t worry too much about little lumps. Season with salt, pepper and nutmeg.

Spread a third of the lentil, vegetable and stock mixture over the base of a large ovenproof dish. Cover with 4-5 sheets or a layer of lasagne and spread half the cheese sauce over the top. Cover with another third of the lentil/vegetable mix, another layer of pasta, the last of the lentils/vegetables, then rest of sauce. Sprinkle with cheese.

Bake for 45 mins until browned. Leave for 10 mins to settle before serving. Serve the lasagne with green vegetables or salad.
